Get your taxes done using TurboTax

Go to the Personal information and filing status and edit.    It is unlikely that TurboTax changed your filing status to HOH unless you already entered a qualifying relative as a dependent since that is a requirement for HOH.  The HOH interview makes you enter your dependent before it will change to HOH.
